I've developed an app using the Google Maps API (V3) and I have some custom map styles defined as described here. I can add a name on this tab quite easily by giving it a 'name' in the styledMapOptions when creating it. The problem I have is that I need the default terrain map in there but with another name/label. I was thinking I could create another custom map type with the terrain as a style option but read that it's not possible here. Could I read out this terrain mapType object and just change the 'name' parameter and throw it in there as a custom mapStyle? Any other ways?
